How Accurate Is PaperYak?
PaperYak's accuracy depends on:
- •Subject consistency: Arts/humanities essays are typically within 1-2 grades of final marks. STEM is slightly less accurate because coding/math assignments vary more widely.
- •Rubric clarity: If you provide a clear rubric, accuracy improves significantly (within 0.5 grades).
- •Your university's style: Some universities mark harder or softer than others. Our feedback is calibrated for UK & US university marking standards.
Bottom line: Use PaperYak to identify weak spots, not to bet your grade on the number. But you'll almost always get useful feedback.
